Having come back to maths after a 15 year break i seem unable to see the woods for the trees. I think i can see that i need to bring the right hand side log to the left of = but stuck after that. I think the 1/2 is confusing me!!!

Its been a long time

Dear wtopping,

Ok. After taking the right hand side log to the left hand side try to apply the log identity I have given you. For this you have take 1/2 out of the bracket first.
